java - 如何从另一个类调用带有参数的方法？

Question

I am coming to a problem where I want to call a method from one class to another, but this method has a parameters. I tried doing String searchData = "searchValue" from my another class, but it for my other class is not being called.

Here is my code:

The method that I want to call

public List<JobSearchItem> getJobAutocomplete(String searchValue) {
    String sValue = "%" + searchValue.toUpperCase() + "%";
    return dataUtilityService.getJdbcTemplate().query(SQL_GET_JOB_SEARCH_LISTS, 
                                new Object[]{sValue, sValue}, jobSearchItemMapper);
} 

the other method that I want to call the above code

public void loadSearchList() throws SQLException, NamingException, URISyntaxException, IOException, ParseException {

   String searchData = "searchValue";
  List<JobSearchItem> jobSearchList = XPayService.getJobAutocomplete(searchData);


    this.setJobSearchItems(jobSearchList);
}

You either need an instance of the XPayService class to call the method on, or else you can make the method static

Using an instance of the class:

class XPayService() {
    public List<JobSearchItem> getJobAutocomplete(String searchValue) {
        String sValue = "%" + searchValue.toUpperCase() + "%";
        return dataUtilityService.getJdbcTemplate().query(SQL_GET_JOB_SEARCH_LISTS, 
                                    new Object[]{sValue, sValue}, jobSearchItemMapper);
    }
}

public void loadSearchList() throws SQLException, NamingException, URISyntaxException, IOException, ParseException {
    XPayService xps = new XPayService();
    String searchData = "searchValue";
    List<JobSearchItem> jobSearchList = xps.getJobAutocomplete(searchData);
    this.setJobSearchItems(jobSearchList);
}

Using a static method:

class XPayService() {
    public static List<JobSearchItem> getJobAutocomplete(String searchValue) {
        String sValue = "%" + searchValue.toUpperCase() + "%";
        return dataUtilityService.getJdbcTemplate().query(SQL_GET_JOB_SEARCH_LISTS, 
                                    new Object[]{sValue, sValue}, jobSearchItemMapper);
    }
}

public void loadSearchList() throws SQLException, NamingException, URISyntaxException, IOException, ParseException {
    String searchData = "searchValue";
    List<JobSearchItem> jobSearchList = XPayService.getJobAutocomplete(searchData);
    this.setJobSearchItems(jobSearchList);
}
